Building envelope / Condominium buildings
Below-grade water ingress investigation for condominiums
Prepare an investigation of water entering below-grade walls, parking or service spaces. Connect indoor observations with the site, drainage and earlier repair history so a qualified provider can define a useful assessment.
The decision this helps you make
What to aim for.
A documented understanding of the observed entry paths, investigation limits and options for further assessment or corrective work.
Envelope work can involve balconies, windows and exterior walls alongside the interiors of affected homes. Start with a record of the observed problem and the association’s existing investigation history before defining a repair package.
Define the scope.
- Identify affected walls, slabs or spaces and describe when water entry occurs.
- List nearby site features and known drainage or waterproofing work for review.
- Ask the provider to separate investigation, temporary measures and permanent corrective options.
Put these records together.
- Collect available below-grade drawings, drainage plans and earlier waterproofing or repair reports.
- Provide dated photographs and observations associated with rainfall or other site conditions.
- Identify access restrictions, adjoining property contacts and any occupied operations affected by investigation.
For condominiums
Fit the work around the property.
A condominium project brings a shared building, individual homes and a group decision into the same conversation. A useful brief starts with the part of the property being considered: a common roof, a shared plant room, a parking area or work that crosses into individual units. Describe the current problem, the evidence already available and the outcome the association wants to discuss. Give the contractor a clear route back to the property manager or board representative who can coordinate questions. Explain how decisions will be reviewed and when residents can expect an update.
Access deserves its own plan because a single appointment may involve several owners, secure doors, elevators and occupied rooms. Record proposed work hours, storage areas and any arrangements for mobility needs. Include the process for investigating hidden conditions before additional work proceeds. At handover, ask for a practical record of completed work, open items and the contact responsible for follow-up. This helps future boards and managers understand what changed without depending on the memory of one volunteer.
Decisions and responsibilities
- Board or council representative coordinating the shared project
- Property manager arranging access, communications and quote comparison
- Affected owners when proposed work enters individual units
Service-specific scope
- Locate reported leaks or deterioration on photographs and a building elevation.
- Identify balconies, patios and rooms where access or temporary changes need coordination.
- Ask how additional findings will be reported for review before scope changes proceed.
Access and operations
- Resident notice and appointment arrangements for occupied units
- Elevator bookings, loading space and secure key control
- A contact for accessibility needs and urgent resident concerns
Questions for the provider
- Who will coordinate appointments across homes affected by the same exterior area?
- How will completed repairs and any unresolved observations be recorded at handover?
Ask for a comparable proposal.
- Define the assessment areas and the assumptions about access to concealed construction.
- Separate testing, opening-up, excavation or specialist input from the initial investigation.
- Ask the report to explain findings, unresolved questions and the basis of each proposed option.
Understand what affects the cost.
Ask providers to price the same scope and explain the assumptions behind these items.
- The depth and accessibility of the affected construction and surrounding site areas.
- The investigation needed to distinguish possible entry paths or connected drainage issues.
- Parking, tenant or neighboring-property coordination and restoration after investigative work.

Project: Below-grade water ingress investigation · Property: Condominium buildings
Agree on the handover.
- Keep a marked location record and photographs documenting the investigation findings.
- Record temporary measures and any monitoring requested by the responsible professional.
- Obtain a separate corrective-work brief with access, restoration and verification responsibilities.
- A location-based list of completed work and outstanding items
- Product information, warranties and maintenance contacts
Questions before you begin.
Should we request excavation as the first step?
Describe the observations and ask the provider to explain an appropriate investigation sequence. Have the proposal distinguish what can be assessed initially and what further access may be needed.
What makes a waterproofing repair proposal easier to compare?
Start with the same investigation findings and affected areas. Ask providers to explain repair boundaries, access, reinstatement, assumptions and verification so the options can be assessed against the same problem.
Who should coordinate below-grade water ingress investigation for condominiums?
Confirm the responsible contact among Board or council representative coordinating the shared project; Property manager arranging access, communications and quote comparison; Affected owners when proposed work enters individual units. Give the provider one person who can supply records, arrange access and take questions back to the decision-maker.
Continue planning.
